I've set up all my slides and positioned the graphs, so they line up nicely on my slides but when I run the votes they seem to shrink and are not lined up. The graphs look too high and too small.
Check the settings on your computer. You need to run voting slides with font zooming set to 100%. A higher percentage will mean that Windows will zoom all the other items on your slide but not the graph, which is why the graph alignment looks wrong.
On the computer, not within PowerPoint, go to Display Settings and scroll down to the Scale & layout section. Then use the drop down to the right of Scale to change it to 100%.
